Project 1 Sequence file missing VIs after working on Project 2 Sequence file.

[Marinuss]

Hello All

I have several TestStand codes for different products, I store each product's TestStand VIs in a separate folder. So when working on one product I don't change the other product's VIs. Or that's what I hope for.

Below are my different products in a separate folder:

Last week I worked on Proloc II_Full_Test_01_22_A_01.seq and got everything to work.

Today I worked on another product (NC_Relay). Then out of curiosity, I opened Proloc II_Full_Test_01_22_A_01.seq again to see if it still runs. Now there are VI's missing. It happened in the past as well. Every time I change to another product the other product gets messed up.

I don't understand why. Each product's VIs are in separate folders. The only common VIs are the OMICRON driver VIs (See below)

What can I be doing wrong, see the Error I get in TestStand. Below

This sounds rather like a file organization issue....

Are the VIs organize in an lvlib for each product? Do some product folders contain VIs with the same name?

Hello Oli

Not sure what lvlibs are, don't think I use it.

The VIs are duplicated in each product folder, so yes most VIs have duplicate names.

I guess, what you are experiencing is an effect of the following: LabVIEW differentiates VIs by name. And it can only have one single VI with a given name loaded in memory at a time.

What could've happend is, that you had two instruments loaded at a time an referring to a VI in their respective folder but with the same name. Only one got loaded and one of the instruments got changed. Maybe there was a Save As dialog (which can also acta as a file move) and you accidentally removed one of the VIs.

You can circumvent issues like this by using lvlibs https://www.ni.com/docs/de-DE/bundle/labview/page/using-libraries-in-labview-projects.html

since they will create namespaces and allow you to load two files which would otherwise be conflicting.
